Stainless Steel Bag Filter Vessel Tank With SS304 / SS316 Material
For Filtration System
Bag Filter Vessel replace the filter bag
1) High-efficiency filter bags are made of fine fibers, which are
less hydrophilic. The surface of the fiber is not wetted by water,
so like other filter
elements that use the same material, it is wetted with other
liquids with a lower surface tension before use. Before
installation, you must
immerse the filter bag in a pre-fluid that matches the filtered
liquid for a few minutes.
2) Open the top cover of the bag filter.
3) Stabilize the top cover and carefully remove the filter bag.
4) Put in a new filter bag, please refer to the installation
process.
Bag Filter Vessel Monitoring the quality of filtration
When the liquid input pressure is stable, the filtration quality is
closely related to the pressure difference in the filter bag. If
the pressure
difference is too large, the filter pore size of the filter bag is
blocked and the filtration speed is lowered. Therefore, we
recommend that when the
bag filter starts working, the pressure difference should be
checked regularly, and the pressure difference displayed by the
front and rear
pressure gauges should be used to determine the time to replace the
filter bag. Generally, the filter bag can withstand a pressure of
0.5-
1Kg/cm2 (0.05- About 0.1Mpa), when the pressure difference reaches
this range, the filter bag should be replaced in time to avoid the
filter bag
from rupturing and affecting the filtration effect.
If the pressure differential drops suddenly, stop the filtration
immediately and check for leaks.
Five, pressurized discharge residual liquid
When filtering high-viscosity liquids, compressed air can be
introduced into the exhaust valve to accelerate the discharge of
the remaining liquid
and shorten the waiting time. Its device is shown in the figure.
Please note: The air used for pressurized discharge must be stable
and the
pressure should not exceed the working pressure of the filter.
The steps are as follows:
1) Close the input valve.
2) Open the intake valve.
3) The gas is introduced into the bag filter, and the remaining
liquid is exhausted.
4) Check the outlet pressure gauge to confirm that the gauge
pressure is equal to the compressed air pressure; confirm that
there is no liquid
outflow at the outlet.
5) Close the intake valve.
6) Slowly open the exhaust valve; the exhaust valve is discharged
at the outlet of the exhaust valve and must be led to a safe place
or filter
suction port.
7) After the compressed air is exhausted, close the exhaust valve.
At this point, there should be no pressure inside the filter, and
the cover can
be opened.
